[PATCH] Documentation/git-update-index.txt: Remove obsolete note

[Jakob Pfender <jpfender@elegosoft.com>]

8dcf39 (Prevent bogus paths from being added to the index) introduced a
check for files beginning with '.', preventing path names such as
`./file`, `dir/./file` or `dir/../file` from being added. This was
reflected in the man page.

d089eba (setup: sanitize absolute and funny paths in get_pathspec())
removed this check without reflecting the change in the man page.
